SGI & NASA Plan 10240-Processor Altix Cluster
green pizza writes "NASA has announced plans to cluster twenty 512-processor Silicon Graphics Inc Altix supercomputers connected to a 500-terabyte SGI InfiniteStorage SAN. The Altix uses Itanium2 CPUs running Linux atop an Origin 3000-derrived architecture. NASA and SGI scaled Linux to 512 CPUs late last year. There are also strong hints that SGI plans to bring its clustered ATI graphics to Altix in the near future. Lots of neat big iron project on the horizon!"
NASA has picked computer maker Silicon Graphics Inc. and chipmaker Intel to develop a major supercomputer based on Linux to simulate space exploration and conduct other research, SGI announced Tuesday.

Well, until the final numbers come out, we aren't speculating on performance. Needless to say we hope to claim the top slot in computing power. Also, keep in mind that parts availability is a major concern. We are assembling the system to be fully up and running by SuperComputing '05 in November. Intel has fully committed to delivering all 10K CPU's with no problems. Also, perhaps the biggest reason for Intel, is SGI was chosen as the vendor and they use Intel.
there are no stupid questions, but there are a lot of inquisitive idiots
Sigh, that's Supercomputing '04 in November. Of this year. Sorry about that.

RTFA:
By boosting its computing capacity ten-fold through Project Columbia, the NASA Advanced Supercomputing Facility (NAS) will be able to more effectively handle such critical projects as simulating future space missions, projecting the impact of human activity on weather patterns, and designing safe and efficient space exploration vehicles and aircraft. The present collaboration builds upon the highly successful 8-year partnership that last year developed the world's first 512-processor Linux server - based on standard, "off-the-shelf" microprocessor and open source technology - the SGI Altix at NASA Ames Research Center named 'Kalpana' after Columbia astronaut and Ames alumna Kalpana Chawla.
Modeling and building on a business relationship.

I have always liked SGI hardware. And congradulations are in order for them to have a single Linux kernel running across 512 CPUs.
In SGIs press release they state that they hope to get the top spot on the 500 list. As all know IBM is expecting Blue Gene http://www.research.ibm.com/bluegene/ to take the top spot in 2005.
It looks like SGIs architecture for the Altix is better than the Blue Gene, but 10,240 intel CPUs is just going to be outpowered by the 65,536 PowerPC CPUs in Blue Gene.
Now the ultimate machine would have SGIs architecute (memory) and #CPUs per node using the PowerPC CPU. We know that IBM and SGI would never colaborate on something like this, but can't a geek dream!

Not yet, but Cray is working on it in something called Red Storm.
Itanium's "better" floating point performance than Opteron is confined to some pretty specialised benchmarks. Over all, Opteron is a more efficient design, runs cooler than itanium, has better compilers, better software support, is cheaper and had more room to scale to much higher clock speeds.

thought that SGI sold a lot of their graphics IP (including many of their top graphics engineers) to NVIDIA a while back, and still have agreements with them. Their IRIX systems sell with VPRO graphics cards, which I believe are repackaged NVIDIA chips with a few extras..
Or did I miss something?
Yes, The Vpro series only resembles Nvidia chipes because after it was completed, most of the team went to work for Nvidia and created the geforce with lots of the same ideas behind it. So the original GeForce chips were more like cut down Vpro's than the VPro's were soupped up GeForces if that makes any sense.
What few people seem to know (and appreciate) is that SGI has been one of the major contributors to Linux over the last few years. Not only XFS, but lots of commands, utilities and system functions have been enhanced, based on IRIX code. This has been a significant boost to Linux, and it's only fair that SGI reaps some benefits.
I wish SGI and its employees the best of luck!
